FEEDING MECHANISM FOR WOOL-CARDING ENGINES.

SPECIFICATION forming part of Letters Patent No.'506,4 87, dated October 10, 1893.

Application filed March 9, 1893. Serial No. 465,365. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL O. FISHER, a citizen of the United States, residing at Allston,'in the county of Sufifolk and State of Massachusetts, have invented certain new and'useful Improvements in Feeding Mechanism for Wool-Carding Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to feeding mechanisms of that class in which the stock is taken from a supply or receiving chamber or space by means of a toothed elevator or tranferrer, and, after being discharged from the latter, is passed onward to the feed-rolls of a carding engine by means of a delivering device, the latter usually being in the form of a traveling endless feed-apron on which the wool discharged from the elevator or transferrer is accumulated.

The object of my invention is to provide improved means whereby automatically to secure uniformity and regularity in the bulk and density of the sheet or layer of wool fed or delivered to the feed-rolls of the cardingengine.

My invention consists especially in the combination with a wool-box having a receiving chamber orspace into which a supply of wool is thrown, and a secondary chamber or space, a toothed elevator or transferrer taking the wool from the receiving chamber or space, means for discharging the wool from the said elevator or transferrerinto the secondary chamber or space, and a deliverer for carrying the wool away from the said secondary chamber or space, of a matter for compacting the, wool over the said deliverer, means for actuating the said matter, variable speed devices for driving the elevator or transferrer, and devices controlled by the movements of the matter whereby the action of the said variable speed devices is regulated and the speed of the elevator or transferrer is altered.

The invention will be described fully with reference to the accompanying drawings forming a part of this specification, and then will be particularly pointed out and clearly defined in the claims at the close of this specification forming a part hereof. v

In the drawings, Figures 1 and 2 are opposite end views of a wool-feeding mechan sm embodying my invention. Fig. 3 1s a view thereof in transverse section, on a plane parallel with the ends of the wool-box.

At 123, in the drawings, is shown a wool box, which may be of any suitable size or shape, and at l is a receiving chamber or space in the said wool-box into wh ch a supply of wool is thrown from time to tlme, as may be required.

At 20 is an endless apron forming the bot; tom of the receiving or supply chamber 1, it being operated in known and usual manner for the purpose of leading or directing the wool to the toothed elevating or transferring device 4. The toothed elevating or transfer-. ring device 4 may be of the character of any of the known devices for performing a similar function, it operating to take or draw the wool gradually from the receiving or supply chamber and carry it into position to be discharged into a secondary chamber 2.

At 31 is a moving comb or evener for removing surplus material from the surface of the elevator or transferrer and returning it to At 21 is a delivering device by means of which the wool discharged from the elevator or transferrer 4 into the secondary chamber or space 2 is carried onward to the feed-rolls 211, 211, of a carding engine, the said delivering device being shown as constituted by the endless traveling feed-apron usually employed, and which in practice may be actuated by any suitable or known means.

In Fig. 1 I have shown the outer roller 212 of the delivering apron 21 driven by gears 213, 214, 215 from one of the feed-rolls 211, and the said apron thereby operated in unison with the said feed-rolls.

At 6 is shown a matting device whereby the wool in'the secondary ohamberor space 2 is pushed forward onto the upper surface of the delivering apron 21 and compacted or matted together'thereon, the said matter acting at each advance thereof topush the wool at the.

bottom of the chamber or space 2 forward onto the apron until it is carried against the Wool alreadyaccumula-ted on the apron, and

then to compress or compact the whole" to a predetermined density. The wool therebyis formed into a-compact lay-erof a thickness dependent upon the height of the throat 3,

which is the space existing between the upper surface of the delivering device 21 and the adjacent surface of a plate or board 22 which may be fixed in position but preferably is pivoted at its forward edge, at 221, and at its rear edge is free to swing toward and .from the delivering device, the plate bearing downward upon the wool, as it is accumulated upon the delivery device, with a pressure proportionate to its weight. I

"At 23 is shown a pressure roller journaled in arms at the free edge of plate 22 and bearing by its periphery against the wool, its weight adding to the pressure exerted upon the wool. The latter is pushed by the matter 6 into the throat 3, and compressed or compacted therein into a layer of suitable density. The matter 6 shown in the drawings is formed of a series of fingers 61 which are secured to a transverse bar or strip 62 that is carried by arms 63 on a vibrating shaft 24.

,At 9;is a guard or grating between the bars or strips whereof the fingers 61 pass, the said guardyor grating serving to strip the wool fromthe fingers 61 as they are retracted,and,.

25 around which passes a driving band 251.

Shaft-12 is provided with a pinion 121 meshing-withagear'll on a shaft 111. At 113 is aradial slot in an arm'of gear 11 in which is adj ustably secured a crank pin 112 with which is connected one end of a rod 14, which rod at 7 its opposite end, is connected to an arm 261 on said ratchet-wheel-are engaged by a pawl 19 pivoted to an arm 16 which isfree to-turnv aroundthe stud supporting the pinion 27 and ratchet-wheel 271, thesaid arm being connected by a link 161 to the rod 14. By these icollar 102, as shown.

inunison. V and the movements of the various parts are crank-disk 15, the pin whereof has connected thereto one end of a-rod 10. At or near its other end the said rod has slipped thereon collars-101,102 which are secured in place at a short distance apar'tb'y clamping screws 103, 103, as shown. Between these collars there is mounted on the rod a sliding collar 104 which is pivotally connected with the arm 7 on one end of shaft 24 of the matter 6. A fourth collar 105 is mounted on the rod 10 {at a suitable distance from thecollars 101, r 102, and 104, it being held in place bya'clampjing screw 106, and to the collar 105 is attached one end of a spring 107 having its other end attached to' the sliding collar 104, ithe said spring being of sufficient strength to "hold the collar 104 normally drawn against On the other'end of Ishaft 24 is an arm 241 which is connected by a rod 18 to a shield or guard 17 that is pivoted on the same stud with the pinion 27 and ratchet wheel 271. tween the arm 241 on the shaft 24 of the mat- "ter 6 and the shield or guard 17 is such as to cause the matter and guard or shield to move The connections are so arranged,

so timed, as will be apparent, that during'the regular working of the mechanism, and as long as the matter is permitted to' move unobstr-uctedly through its usual length of stroke, the guard or shield 17 will be withdrawn or moved away from the pawl 19 just prior to the advancing movement of the latter in which it engages with and turns the ratchet wheel 271, leaving it free to engage with the ratchet-wheel and advance it the predetermined maximum number of teeth, thereby rotating the elevator or transferrer at its highest or maximum rate of speed.

' It will be observed that'in the case of the wool accumulating in the throat 3 at a rate faster than the delivery device passes it onward to the feed-rolls of the carding-engine, the advance of the matter will be resisted until the point is reached at which the spring 107 yields, when the matter will be arrested in its advance, the extent to which it is advanced depending upon the amount of wool which has accumulated in the throat 3. In consequence of the arrest of the advancing movement of the matter, the guard or shield will be withdrawn only partially from the The connection be space 2. The elevator or transferrer will continue to be rotated at a reduced rate of speed proportionate to the extent of theaccumulation of wool'in the throat 3, as willb'e under.- stood, until the wool on the delivery device has been passed on to a sufficient extent to permit of the matter being moved byits actuortransferring device;,also, I wish it to be understood that the illustrated forms of variable-speed devices whereby said elevator or transferrer is actuated, the matter itself, the means for operating the'same, and the connections through which the matter in its movements serves to control the action of the said variable-speed devices, may variously be modified in minor mechanical respects and replaced by their mechanical equivalents without any departure from the spirit of my invention.

On the under side of the board 22 are provided teeth 22l for holding the wool which has been crowded into the throat 3 by the matter from returning with the said matter.
